The Jumanji movies have seen four total releases in the series, with only three using the actual franchise name. What started as a children’s picture book in 1981 has become a genuine franchise, with the first four films grossing more than $1 billion worldwide over three decades, and have enjoyed a surprising amount of critical success. The original Chris Van Allsburg book introduces Judy and Peter Shepherd, who encounter a game called Jumanji that transports them into it real-life animals and all.
